Summary

Image of the Crab Nebula in Infrared at 3.6 (blue), 5.8 (green) and 8.0 (red) µm. The image has been made by myself (Médéric Boquien) from the public image archive of the Spitzer Space Telescope (courtesy NASA/JPL-Caltech). For each band, the *maic.fits images were combined using IRAF imcombine with the parameters combine=median; reject=none; offsets=wcs. The final colour image was made using DS9 with the following command line: ds9 -rgb -red ch4/pbcd/ch4.fits -scale limits 10 60 -green ch3/pbcd/ch3.fits -scale limits 3 50 -blue ch1/pbcd/ch1.fits -scale limits 1 15 -view colorbar no.
